IMPROVEMENT IN SHIPS PUMPS. I

Specification forming part of Letters Patent No. 154,233, dated August18, 187i application filed May 29, 187 4.

the pumps now in use for raising and discharging Water from ships, andfor other purposes. The invention will first be fully described,

and then pointed out in the claim.

In the accompanying drawing, Figure 1 shows a vertical section of thepump. Fig. 2

is a vertical section on the line as a: of Fig. 1. Fig. 3 is a detail,showing the conical tube in perspective.

Similar letters of reference indicate correspondin g parts.

This is a double-cylinder liftingpump, the pistons of which areoperatedby means of levers in a vibrating socket-beam, to which the piston-rodsare attached.

AA are the cylinders; B B, the pistons; O O, the piston-rods; and D, thelever-beam, which is vibrated 0n the central pin E. F is base of thepump, upon which the cylinders rest. G is the inductiQnpipe; H, theair-chamber. I is the reservoir at the foot of each cylinder. J is aconical tube at the foot of each cylinder, the lower ends of whichextend down into the reservoirs, and are always immersed in water. Theseconical tubes have (each) a surrounding flange, K, by means of whichthey are supported in thebase on the inwardly-projecting ledges L, asseen in Fig. 1, and are held in place by the cylinders, with packing mbetween, to secure water-tight joints. N N are the drop-valves of thecylinders. These valves are fitted to and dropped into the conical tubesJ J. Orepresents a bail on each of these valves,

by means of which they may be lifted out through the cylinder by takingout the central pin E and removing the pistons. In pumps of ordinarysize the hand may be inserted for this purpose, or they may be liftedout with a hook, as may be desired, without disturbing a bolt or nut.

To prevent freezing, the water is withdrawn from the reservoir by meansof small screwplugs I. The water in the reservoir (except when drawn offby removing the plugs P) always stands above the lower ends of theconical tubes J, and serves as a constant priming, the pistons alwaysbringing water at the first strike.

Q is a rubber cushion on each of the cylinders, on which the lever-beamI) impinges when the pump is worked. These cushions are confined insockets R, and serve to deaden the noise and ease the shock for menworking the pump. S is the discharge-pipe.

These pumps may be made of any required size, and be placed in anydesired position for raising and discharging bilge-water, or for otherpurposes on ship-board, or to be used elsewhere for all the purposes forwhich they may be adapted.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- The combination of the conical tubes, having flangeK, and supported on ledge L, with the reservoir and induction-pipe,arranged as shown and described, for the purpose specified.
